No way, i hate when people show up places with sick kids, its very rude and inconsiderate. it is never ok, if your child is sick you stay home or at least away from other people. i have a set of friends who's kids are always sick, they try and tell me its allergies, i have kids too i know a sick kid when i see one and it irritates me, i will leave the place if someone shows up with sick kids, its not worth it to me to stayand chance my kids catching something they can avoid
